The design task of high-speed passenger flight across the Pacific Ocean was addressed by four design teams of eight students each. Two teams examined hypersonic flight (Mach greater than 5) and two teams studied supersonic flight (Mach = 3). The specific task of the aircraft was to transport at least 250 passengers 6500 nautical miles while operating from airport runways of 15,000 feet. Four design concepts evolved; the supersonic designs--one a variable-sweep oblique wing and the other a cranked-arrow wing--use conventional turbine engines and liquid hydrocarbon fuels. The two hypersonic configurations, one with a variable-sweep wing and the other with a fixed, swept-wing planform, employ methane fueled, variable-cycle turbojet/ramjet propulsion systems. Both supersonic aircraft weigh less than 700,000 lbs at takeoff, while the variable-geometry hypersonic airplane is the heaviest at 1,100,000 lbs and weighs 170,000 lbs more than the fixed-wing hypersonic design. All the conceptual designs are shown to perform the transport mission, although development and operating cost estimates favor the supersonic designs over the hypersonic configurations.
